PHP代码:--------------------------------------------------------------------------------
function ccStrLen($str) #计算中英文混合字符串的长度
{
$ccLen=0;
$ascLen=strlen($str);
$ind=0;
$hasCC=ereg("[xA1-xFE]",$str); #判断是否有汉字
$hasAsc=ereg("[x01-xA0]",$str); #判断是否有ASCII字符
if($hasCC && !$hasAsc) #只有汉字的情况
return strlen($str)/2;
if(!$hasCC && $hasAsc) #只有Ascii字符的情况
return strlen($str);
for($ind=0;$ind {
if(ord(substr($str,$ind,1))>0xa0)
{
$ccLen++;
$ind++;
}
else
{
$ccLen++;
}
}
return $ccLen;
}
function ccStrLeft($str,$len) #从左边截取中英文混合字符串
{
$ascLen=strlen($str); if($ascLen $hasCC=ereg("[xA1-xFE]",$str); #同上
$hasAsc=ereg("[x01-xA0]",$str);
if(!$hasCC) return substr($str,0,$len);
if(!$hasAsc)
if($len & 0x01) #如果长度是奇数
return substr($str,0,$len+$len-2);
else
return substr($str,0,$len+$len);
$cind=0;$flag=0;
while($cind {
if(ord(substr($str,$cind,1)) $cind++;
}
if($flag & 0x01)
return substr($str,0,$len);
else
return substr($str,0,$len-1);
}
